On October 16 I posted – October in Australia cooling off after record September heat. That trend has carried on with November being cooler than October.

Australia has seen a series of record 12 month running average warm mean temperatures.

Each monthly BoM statement discusses the above. The data for my graphic is obtained here – Australian climate variability & change – Time series graphs

I am curious if there are meteorological explanations for the three similar sharp mean temperature peaks in 2005, 2009, 2013.
